Still, using a 3D printer isn't always simple: The machine is frequently housed within a box the size of a microwave, and it requires technical software and, in some cases, a detailed knowledge of design. In 2012, Maxwell Bogue and Peter Dilworth, co-founders of 3Doodler along with Daniel Cowen, were trying to come up with the next great kids' toy. The two wished they "could just take the nozzle off the 3D printer and fill in the missing gap," Bogue, now CEO of the company, told Live Science.
